# trezor-emulator MCP
MCP server for controlling Trezor emulators running inside `trezor-user-env` Docker container.
## How it works
Connects to the `trezor-user-env` WebSocket API on port 9001 to send commands (start/stop, click, input, setup, etc.) and captures screenshots via VNC on port 5900.
## Requirements
- `trezor-user-env` Docker container running with port 9001 exposed
- VNC on `localhost:5900` (for `emulator_screenshot`) — requires the [`feature/x11-to-vnc-migration`](https://github.com/trezor/trezor-user-env/tree/feature/x11-to-vnc-migration) branch of `trezor-user-env`
- `python3` with `venv`
## Setup
Run `./run.sh` — it creates `.venv` (or uses `$TREZOR_EMULATOR_VENV`), installs dependencies, and starts the server.
### MCP config example (VS Code)
```json
{
"servers": {
"trezor-emulator": {
"type": "stdio",
"command": "/usr/bin/env",
"args": [
"bash",
"/absolute/path/to/trezor-emulator-mcp/run.sh"
]
}
}
}
```
